Waterproof performance: Up to 1m depth (10 minutes), as for JISB7261 (ISO9022-8) test with an estimated 7 IPX (10 minutes).

First things first. The great advantage of ED glass lenses is that the change in the reflective index within the wavelength ranging from blue to red will be very small. In plain terms, it means the ED glass lenses drastically suppress aberration, whose tangible effect will be the sensation of a naked-eye, natural view.

Dielectric coatingCompared to porro prism, the roof prism of these binoculars offers a superior optical performance with the advantage of a simpler and comfortable style. But that is far from enough.In order to achieve extremely high levels of light transmission even in compact format binoculars, Avantar binoculars have been provided with the so-called “dielectric coating”. It consists of several “dielectric” layers applied to the prisms that produce no light loss. The word “dielectric” means “no electric conduction”, being this coating non-metallic unlike other binoculars. In practice, it means a marked improvement in brightness.So, with this dielectric coating technology, Avantar binoculars series guarantees high brightness and contrast, high sharpness even while observing small details, and a great performance even when the daylight is fading, or when you are enjoying your outdoor experience in the twilight.

Multi coatingIf you are looking for high standard binoculars, you should know coating is never enough.That’s why in Avantar binoculars, the roof prism has been provided with a phase coating to correct the phase shift, and the auxiliary prism have been covered with dielectric multilayer films for ultra-high reflectivity.Also, by applying a multi- coating (multilayer film coat) to all of the lenses and prisms surfaces, these binoculars achieve a higher capacity of light transmittance.High resolution and contrast are guaranteed.

Waterproof and shock resistantWe know the external matters, too.That’s why waterproof, durable die-cast aluminum body of Avantar binoculars represents the ultimate choice for those customers who want to enjoy the highest grade of outdoor watching experience.If you are eager to know more technical details, the nitrogen gas filling the interior parts prevents any lens fogging.And waterproof performance is up to 1m depth (10 minutes), as for JISB7261 (ISO9022-8) test with an estimated 7 IPX (10 minutes).

Twist-up eyecups and light weightThe clean design of these binoculars offers a high eye point of 17mm eye relief. It means less fatigue for your eyes even after a long period of usage.The twist-up eyecups make the binocular series easy to use even for those customers who wear glasses.But in outdoor events eye relief is not the only thing that matters. That’s why these binoculars adopt a durable but lightweight (630g) die-cast aluminum body.For an even more comfortable sensation, the rubber exterior parts make these binoculars easy to grip and naturally fit your hands.Just hold and relax.
